Abstract:The phase-looked loop (PLL )frequency synthesis for miniature,high-speedacquisition receiver is researched in this paper. Wide-band PLL and voltage preset methodare proposed to improve the frequency agile speed.Band stop filter and phase compensation circuit are used to improve the spur performance and stability of wide-band PLL. Dueto using advanced MMIC PLL and VCO,the researched frequency synthesizer has smallvolume,fast switching speed and low phase noise.
Keywords:phase lock frequency synthesizer  frequency agility  fast transformations
